pray that my son Willis will get a job and his right mind will be restored to him---thank you

PLEASE pray for my son-age 24--he is going through some bad things right now and has for about a year--I don't know what is going on--but he is very depressed and unhappy--he still lives at home--but I believe someone is blackmailing him or he is involved with some drug dealers. I stay so sick about him--that I don't have a life--Pray for God to deliver him from this situation and for God's will to be done in his life. I lost my oldest son to drugs in 2006--he had a rough childhood---it's hard to love with--but this son--my youngest-John-had a really good childhood--raised in church--Christian schools--God I just don't know what to do.
